Background

The airplane of a part of specific types requires simple and compact structure and reliable performance, so that a plurality of special-shaped parts and curved-surface parts are arranged on the airplane, in order to ensure the connection reliability between the accessories, the airplane is usually designed to be installed in an over-positioning mode, connection holes between the accessories need to be processed in a coordinated mode (the coordinated processing is that after two parts are installed and positioned, the lower part or the upper part is convenient for construction parts, the parts are roughly and finely reamed from bottom to top or from top to bottom, and after the holes are roughly and finely reamed, precise bolts are inserted for assembly), the main cross beam of the airplane is assembled with the support arm accessories, namely 8 mounting holes of the main cross beam of the airplane are formed, and. Because of the following reasons, the mounting hole on the main beam and the mounting hole on the support arm fitting can not be directly machined by a machine tool, but the fitting and the main beam are cooperatively assembled: 1. the main beam mounting surface and the support arm mounting surface are inclined surfaces; 2. the deflector rod on the support arm is associated and coordinated with the cabin door opening and closing mechanism. Therefore, the airplane fittings are usually well matched with the fittings of the upper first-level in function debugging, and after the positions of the airplane fittings are determined, the large fittings and the main cross beam are installed after being cooperatively reamed and hinged. At present, a special tool is lacked, so that the machining efficiency is low, the machining quality is poor, and the assembly production cost is high.

Disclosure of Invention

The invention aims to overcome the defects of the prior art and provide the cutting device for the coordinated machining of the connecting hole, which has the advantages of simple structure, high production efficiency and good hole coaxiality.

In order to solve the technical problems, the invention adopts the following technical scheme:

the utility model provides a cutting device for hookup hole coordination processing, includes hangs scraper body and cutter arbor, be equipped with clamping section and installation section on the cutter arbor, hang scraper body suit in on the installation section and the diameter is greater than the diameter of clamping section, hang scraper body is close to the one end of clamping section is equipped with a plurality of cutting edges along the circumferencial direction interval.

As a further improvement of the above technical solution: the diameter of clamping section is greater than the diameter of installation section, the cutting blade with clamping section butt, the scraper body is kept away from the one end of clamping section is equipped with the locking taper hole, the locking taper hole with be equipped with the locking taper sleeve between the installation section, be equipped with the lock nut who is used for fixed locking taper sleeve on the installation section.

As a further improvement of the above technical solution: the locking taper sleeve is provided with an opening and closing seam.

As a further improvement of the above technical solution: and a chip cutting groove is formed between every two adjacent cutting edges.

As a further improvement of the above technical solution: the clamping section is provided with at least one pair of flat parts.

Compared with the prior art, the invention has the advantages that: the cutting device for coordinated machining of the connecting holes, disclosed by the invention, has the advantages that the hanging scraper body is sleeved on the mounting section of the cutter bar, the positioning effect of the connecting holes in the main cross beam can be realized, the positioning effect of the connecting holes in the support arm accessories can be realized by the cutter bar, the clamping section of the cutter bar can be clamped by a hand and an electric drill, so that the hanging scraper body is driven to rotate, the connecting holes of the support arm accessories are hung and cut by the cutting edge part after the connecting holes in the main cross beam are positioned, the problem of coordinated assembly machining of the connecting holes is well solved, the coaxiality of the cut holes is high, the production efficiency is high, the quality is reliable, the economical efficiency of product repair is.
